3.在服务器中创建属于自己的目录 mydata

mkdir mydata

3.下载下来之后上传到服务器mydata 目录下

解压命令

tar xvJf ffmpeg-master-latest-linux64-gpl.tar.xz

4.查看是否缺少依赖

ldd /mydata/ffmpeg-master-latest-linux64-gpl/bin/ffmpeg

        linux-vdso.so.1 (0x00007ffebe5ab000)
        libm.so.6 => /usr/lib64/libm.so.6 (0x00007fb3b102a000)
        libdl.so.2 => /usr/lib64/libdl.so.2 (0x00007fb3b0e26000)
        librt.so.1 => /usr/lib64/librt.so.1 (0x00007fb3b0c1e000)
        libpthread.so.0 => /usr/lib64/libpthread.so.0 (0x00007fb3b0a00000)
        libc.so.6 => /usr/lib64/libc.so.6 (0x00007fb3b0666000)
        /lib64/ld-linux-x86-64.so.2 (0x00007fb3b133a000)
        libmvec.so.1 => not found  #注：明显 libmvec.so.1 => not found 是缺少的

5.下载glibc
我这里下载的是2.25版本的
http://ftp.gnu.org/gnu/glibc/glibc-2.25.tar.gz

执行解压

tar -zxvf glibc-2.25.tar.gz
# 进入已解压的文件
cd glibc-2.25
# 创建构建文件目录
mkdir build
# 进入目录
cd build
# 编译 编译安装
../configure --prefix=/usr
make -i
make install -i

6. 添加环境变量

vi /etc/profile

image.png

unset i
unset -f pathmunge
# 添加这一句
export PATH=$PATH:/mydata/ffmpeg-master-latest-linux64-gpl/bin

让环境生效

source /etc/profile

7.执行查看安装版本

[root@localhost /]# ffmpeg -version
